NumPy 1.19.2 released

Charles R Harris
Hi All,

On behalf of the NumPy team I am pleased to announce that NumPy 1.19.2 has been released. This release fixes several bugs, prepares for the upcoming Cython 3.x release. and pins setuptools to keep distutils working while upstream modifications are ongoing. The aarch64 wheels are built with the latest manylinux2014 release
that fixes the problem of differing page sizes used by different Linux distros.

There is a known problem with Windows 10 version=2004 and OpenBLAS svd that we are trying to debug. If you are running that Windows version you should use a NumPy version that links to the MKL library, earlier Windows versions are fine. 

This release supports Python 3.6-3.8. Downstream developers should use Cython >= 0.29.21 when building for Python 3.9 and Cython >= 0.29.16 when building for Python 3.8. OpenBLAS >= 3.7 is needed to avoid wrong results on the Skylake architecture. The NumPy Wheels for this release can be downloaded from PyPI, source archives, release notes, and wheel hashes are available from Github. Linux users will need pip >= 0.19.3 in order to install manylinux2010 and manylinux2014 wheels.
